IMPROVEMENT IN DEVICE FOR REMOVING- DU'ST FROM THRBSHING-MIACHINES.

To all whom 'it may concern Be it known that I, ERA ROSE, of Vernon, inthe county of Jennings, and State of Indiana, have invented a new andusefulImprovement in Removing Dust from Threshing-Machines; and'I dohereby declare that the following is a full, clear, and exactdescliption ot' the construction and operation of the same, referencebeing had to the accon'lpanying drawings, making a part of thisspecification, in which my invention is represented by a longitudinalvertical section. I y

The object of this invention is to provide for use, in connection withthreshing-niachines, a simple, cheap, aml convenient apparatus, whichcan be employed to take up and remove the dust from thethreshing-apparatus, delivering it outside of the building in which themachine'is used, or in any other convenient place.

In the drawings A represents the frame of the machine;

B, the pipe, which takes up the dust from the thrcshing-cylimier, anddelivers it to the fan;

0, a larger discharge-pipe,-which conducts the dust away fronrthe fan,and delivers it at any convenient point;

I), a partial-dischargepipe, provided with a'pert'orated screen, (I, anda damper-valve, d

E, the fan-box; and

1*, a rotary fan, opeiated by a belt and pulley from the power thatdrives the machine.

The fan-box' E is in the form of a short cylinder, placed transverselywith relation to the conductingpipe, and having the fan arranged withinit, as shown in the drawing.

The Schedule referred to in these Letters Patent and making part of thesame.

' The pipe 0 leads directly from the. lower edgeof the box, so that thewings of the fan, revolving with the sun, will force a strong currentot'air directly into it from the fan-box.

The end ofthe pipe 1 does not enter at the edge, but at the end of thefan-box, as shown at. o, and the nearer i'tcnters to the shaft of thefan, the better will he the draught of air through the pipe, and themore efi'ectirely will the fan force out, into pipe 0, any straws,sticks, 850., that may clmnce to come over.

A pipe or hose, ot'cloth, lndia rnhhcr, or other snitahle material, maybe attached to the delivery-end of pipe 0, '(as shown in red,) for thepurpose of conducting away the dust to any convenientpoint.

Havingthns described my invention,

, What I, claim as new, and desire to secure by Letters Patent, is-

The attachment to threshing-machines herein described, when constructedand operating as set forth, that is to say, having the small pipe B b b,the. large 'pipe 0, the fan 1* and the partial-discharge pipe 1),

with damper (I' and screen (I, all arranged and erm: ing in connectionwitneach other, as and for the purposes specified.

To the above specification of my improvement, I hvwe set my hand, this10th day of April, 1869.
